TPS2044ADR Description

Short technical summary and product information.

The TPS2044ADR from Texas Instruments is a power distribution switch designed for applications with heavy capacitive loads and potential short circuits. It incorporates four 80-mΩ N-channel MOSFET high-side power switches in a single package, each controlled by an independent logic enable input.

 

This device operates within a voltage range of 2.7 V to 5.5 V and provides a continuous current of 500 mA per channel. It includes independent thermal and short-circuit protection with an overcurrent logic output. The switch type is general purpose, with an output configuration as high-side and an input type that is non-inverting.

 

Key electrical characteristics include a typical Rds On of 80 mOhm and fault protection features such as current limiting, over-temperature protection, and undervoltage lockout (UVLO). The interface is a simple On/Off control.

 

The TPS2044ADR is available in a 16-SOIC surface mount package. The operating temperature range is specified from 0°C to 125°C (TJ), with datasheet values indicating 0°C to 85°C.
